    Abstract: Disclosed herein is a process for preparing an isomeric mixture comprising a major amount of a para-linear mono-alkyl-substituted hydroxyaromatic compound. The process involves the steps of: (a) providing an isomeric mixture comprising a major amount of a para-di(alkyl-substituted)aromatic compound; wherein a first alkyl substituent is a C3 to C8 alkyl moiety and a second alkyl substituent is a C4+n to C8+n linear alkyl moiety, wherein n is 0 to 42 and further wherein the second alkyl substituent is at least one carbon atom greater than the first alkyl substituent; (b) subjecting the isomeric mixture comprising a major amount of a para-di(alkyl-substituted)aromatic compound to oxidation conditions in the presence of an oxygen-containing source, thereby converting the first alkyl substituent which is a C3 to C8 alkyl moiety to a hydroperoxide-containing substituted moiety to produce an isomeric mixture comprising a major amount of a para-linear alkyl-substituted, hydroperoxide-containing substituted aromatic compound; and (c) converting the hydroperoxide-containing substituted moiety to a hydroxyl moiety thereby providing an isomeric mixture comprising a major amount of a para-linear mono-alkyl-substituted hydroxyaromatic compound.

    Abstract: A method to determine the strength of an acid in a medium is disclosed. The method includes (I) providing multiple samples comprising trimethylphosphine oxide (TMPO), the acid, and the medium, wherein the multiple samples have different [H+]/[TMPO] ratios, [H+] is the concentration of hydrons in the sample in mole·liter−1, and [TMPO] is the concentration of TMPO in the sample in mole·liter−1. (II) The 31P chemical shifts of the multiple samples are measured by 31P NMR and compared to standardized samples to determine the acid strength of the medium.

    Abstract: In a process for producing phenol and/or cyclohexanone, cyclohexylbenzene is contacted with an oxygen-containing gas in the presence of an oxidation catalyst under oxidation conditions effective to produce an oxidation effluent comprising cyclohexylbenzene hydroperoxide. At least a portion of the oxidation effluent is then subjected to a concentrating step to produce a cleavage feed having a higher concentration of cyclohexylbenzene hydroperoxide than the oxidation effluent. A cleavage reaction mixture comprising the cleavage feed is then contacted with a solid acid catalyst in a cleavage reaction zone under conditions effective to produce a cleavage product comprising phenol and cyclohexanone.
